The cause of death for ‘Glee’ actor Cory Monteith has been confirmed by the Coroner’s Office in British Columbia. Sadly, it’s what we all feared. The office announced on Tuesday that the actor died from the lethal mixing of heroin and alcohol.

Monteith was found dead in his Vancouver hotel room in British Columbia, over the weekend, when he failed to check out of his hotel suite. His body was then discovered by hotel staff who went looking for him.
